Tiffen Deep Blue 47 Filter w/ Red Rocks
Red Rock Canyon [California] State Park.
They’re more orange than red, and the compliment of orange is blue - so I picked up a 52mm Tiffen deep blue 47 filter. It was the least expensive 47 I could find.
This was a demonstration/test of the Tiffen deep blue 47 filter with sandstone formations that have red/orange accents. I like it. I got mixed results with the red-blind ortho film. The x-ray film has a wonky contrast curve that doesn’t have pictorial merit. I didn’t bother to publish that result on Flickr. Ilford’s Ortho Plus looks decent enough, but I don’t have any in sheet film, nor am likely to ever since it is so pricey, so that was just an academic exercise. Kodak's 2422 has promise, but I'm size limited by my 5" wide roll. I’m still testing other ortho film with the red/orange rocks.
Normally I wouldn’t use a sheet of 8x10 for a test, but this is that defective/streaky Shanghai GP3 100. Still, as previously mentioned, the streaks are not noticeable where there is a lot of texture. It can still have utility so long as the composition doesn’t have any negative space.
I adjusted exposure 2 ⅓ stop per Tiffen’s guidance; however, it should be noted that Kodak recommends 2 ⅔ stops adjustment for 400TX and 320TXP; 3 stops for TMX; and 3 ⅓ stops for TMY. ilford recommends 3 stops adjustment for HP5 plus. I couldn’t find any other deep blue 47 filter exposure adjustment recommendations for other films. In this instance, the 2 ⅓ stop appears to be spot on.

Shanghai GP3 100 @50 [the defective streaky stuff]
Rodinal 1:50 for 9 minutes @ 20°C
Some front rise combined with front forward tilt resulted in vignetting in the sky. Really not all that bad, and could easily be digitally edited out. Good to know that the limits of the lens were approached, but not exceeded.
